Application October 20,

1 Claim.

This invention relates to woven fabrics, more particularly to types such as plushes, velvets and i the like, woven to produce two uniformly spaced webs, connected by fine transverse fibers, severed intermediate the webs to form two independent pieces each having a furry appearance, known as cut pile fabrics.

Ordinarily, the cutting is so performed that the pile is of uniform length, that is, the ends of the cut strands are level and parallel with the web in which they are interwoven throughout the entire width and length of the fabric.

An object of the present invention is to provide a cut pile fabric having an undulating, wave-like face, novel with respect to the level surface of ordinary pile fabrics.

A further feature is in the provision of means for cutting a woven double pile fabric intermediate its webs, so that the pile in one portion varies in length from that in another portion, whereby a series of regular undulations are produced throughout the length of the piece. 7

These objects are attained by the novel and practical mechanism hereinafter described and illustrated in the accompanying drawing, constituting a material component of this disclosure, and in which- Figure l is a plan view of a mechanism, made in accordance with the invention, for shearing the woven double web of fabric.

Figure 2 is a sectional View taken on line 22 of Figure 1.

Figure 3 is a transverse sectional view of one of the roller cams between which the fabric passes.

Referring in detail to the drawing, the numeral I5 designates in general the pile fabric as woven, consisting of two webs I5 and ll, between which are the interwoven pile threads. 18.

A stand, composed of side frames 25-25, which may be part of or attached to the delivery end of a loom, is provided with bearings for a plurality of transverse shafts, on one of which 21, is secured a spur gear 28, meshed with'an intermediate gear 3!! on an idler shaft 3|.

An upper feed gear 32, on shaft 33, meshes with gear 30 and also the upper gear 34 of a pair of gears, one of which, 34 is rotatable on shaft 35 and its mating gear 36 on shaft 31, the gear 36 1938, Serial No. 235,997

meshing with the lower feed gear 38 on shaft 39, directly below gear 32.

A tractive roll 4!] is fixed on shaft 27 to extend between the housings 25-26, and over which one of the split webs is trained, as l6.

Fixed on the upper driven shaft 33 is a long face cam 42, a mating cam 43, being secured on the shaft 39, and as the shafts are driven in unison, the cams operate in timed relation.

Each cam, 42-43 is shaped to produce slightly raised surfaces 45 arranged longitudinally at ninety degrees apart, while therebetween are dia-. metrally reduced spaces 46, the cams being so adjusted on their respective shafts that the raised portions of one are directly opposite the lowered portions of the other, so that the fabric in passing between them is alternately raised and lowered, from a level plane, a distance corresponding to the regular undulations of the cams.

Fixed between the frame elements 25-4! is a stand 48 preferably having an undercut plate surface 49,:to which may be fitted a slide as provided with a clamp 5| by which is secured a keen bladed cutting knife 52, disposed longitudinally of the cams centrally of the oncoming fabric i5.

It will now be seen that the fabric as woven, passes between the cams 42-43, by which it is moved up and down, relative to its normal plane,

and therefore the pile is cut to produce an undulating surface, as at Iii-2!], as the web. [6 is drawn over the tension roll 40.

Although the foregoing is descriptive of the best known embodiment of this simple device, it is not to be held as restrictive, as many modifications may be made within the scope and'tenor of the appended claim.

Having thus described the invention and set forth the manner of its construction and application what is claimed as new and sought to secure by Letters Patent, is:

In a machine for splitting a double web pile fabric, a fixed knife, means to feed the fabric against said knife, a gear train, and a pair of rotating cams having undulated faces, one above and the other below the fabric web, closely adjacent the edge of said knife, whereby the pile threads between the webs are severed to present undulating surfaces when cut.
